The management of abdominal hydatidosis after the rupture of a pancreatic hydatid cyst: a case report
2015
Introduction Echinococcosis or hydatidosis is a zoonosis caused by cestodes from the genus Echinococcus; its habitat is the small intestine of the definitive host, represented by dogs/carnivorous animals, where it produces eggs which are eliminated in the environment. Cystic echinococcosis represents more than 95% of the hydatidosis cases registered annually. The most frequent localization is the hepatic one, followed by the pulmonary localization with a ratio of 2.5:1. A pancreatic localization represents 0.2% of hydatidosis cases with a higher possibility of disseminating intra-abdominally. The incidence of hydatidosis in Romania has not been investigated yet through national studies. Cas…
Multiple intrahepatic pseudocysts in acute pancreatitis
2007
Liver pseudocysts are a very rare complication in acute pancreatitis with only a few cases previously described. The lack of experience and literature on this condition leads to difficulties in the differential diagnosis and management. We report herein a case of acute pancreatitis who developed multiple intrahepatic pseudocysts. After complete imaging evaluation, the diagnosis was still unclear and the patient was operated on. The presence of liver lesions in patients with acute pancreatitis should raise the possibility of intrahepatic pseudocysts.
Circulating TNF-alpha and its soluble receptors during experimental acute pancreatitis.
2004
Clinical and experimental studies have shown increased concentrations of TNF-α and its soluble receptors in serum of patients with acute pancreatitis. In this work, we have investigated the time-course of TNF-α and its soluble receptors during taurocholate-induced acute pancreatitis. In addition, since TNF-α itself could mediate the shedding of its receptors, we have assessed the effect of inhibiting TNF-α production on the release of soluble TNF-α receptors in experimental acute pancreatitis. Our results indicate that soluble receptors are released in the early stages of the disease and this increase is concomitant with the release of TNF-α, which is mainly bound to specific proteins. The …
Pancreatic T cell protein-tyrosine phosphatase deficiency ameliorates cerulein-induced acute pancreatitis.
2014
Background Acute pancreatitis (AP) is a common clinical problem whose incidence has been progressively increasing in recent years. Onset of the disease is trigged by intra-acinar cell activation of digestive enzyme zymogens that induce autodigestion, release of pro-inflammatory cytokines and acinar cell injury. T-cell protein tyrosine phosphatase (TCPTP) is implicated in inflammatory signaling but its significance in AP remains unclear. Results In this study we assessed the role of pancreatic TCPTP in cerulein-induced AP. TCPTP expression was increased at the protein and messenger RNA levels in the early phase of AP in mice and rats. To directly determine whether TCPTP may have a causal rol…
Redox signaling in acute pancreatitis
2015
Acute pancreatitis is an inflammatory process of the pancreatic gland that eventually may lead to a severe systemic inflammatory response. A key event in pancreatic damage is the intracellular activation of NF-κB and zymogens, involving also calcium, cathepsins, pH disorders, autophagy, and cell death, particularly necrosis. This review focuses on the new role of redox signaling in acute pancreatitis. Oxidative stress and redox status are involved in the onset of acute pancreatitis and also in the development of the systemic inflammatory response, being glutathione depletion, xanthine oxidase activation, and thiol oxidation in proteins critical features of the disease in the pancreas. On th…
Impairment of PGC-1 Alpha Up-Regulation Enhances Nitrosative Stress in the Liver during Acute Pancreatitis in Obese Mice
2020
Acute pancreatitis is an inflammatory process of the pancreatic tissue that often leads to distant organ dysfunction. Although liver injury is uncommon in acute pancreatitis, obesity is a risk factor for the development of hepatic complications. The aim of this work was to evaluate the role of PGC-1&alpha
Biliary Pancreatitis: Endoscopic Diagnostic and Therapeutic Techniques
1987
Acute pancreatitis constitutes one of the most hazardous emergencies in clinical gastroenterology. Although the diagnosis “biliary pancreatitis” is often used in clinical practice for patients presenting with concrements in the biliary tree or impacted in the papillary orifice [17, 32], the common phrase “biliary pancreatitis” has not so far been exactly defined. Patients with cholecystolithiasis may be included in this group, as well as patients with dysfunction of the sphincter of Oddi. Some authors have reported that juxtapapillary diverticula increase the risk for development of biliary pancreatitis [28].
Pancreas and Cystic Fibrosis: The Implications of Increased Survival in Cystic Fibrosis
2007
Background: In acute pancreatitis (AP), pancreatic necrosis (PN) is an important local complication that can be identified by means of contrast-enhanced computed tomography (CECT).
Pentoxifylline and Oxypurinol: Potential Drugs to Prevent the “Cytokine Release (Storm) Syndrome” Caused by SARS-CoV-2?
2020
Background: COVID-19, caused by SARS-CoV-2, is a potentially lethal, rapidly-expanding pandemic and many efforts are being carried out worldwide to understand and control the disease. COVID-19 patients may display a cytokine release syndrome, which causes severe lung inflammation, leading, in many instances, to death. Objective: This paper is intended to explore the possibilities of controlling the COVID-19-associated hyperinflammation by using licensed drugs with anti-inflammatory effects. Hypothesis: We have previously described that pentoxifylline alone, or in combination with oxypurinol, reduces the systemic inflammation caused by experimentally-induced pancreatitis in rats. Pentoxifyl…
Co-administration of pentoxifylline and thiopental causes death by acute pulmonary oedema in rats
2006
Background and purpose: Pentoxifylline exhibits rheological properties that improve microvascular flow and it is widely used in vascular perfusion disorders. It also exhibits marked anti-inflammatory properties by inhibiting tumour necrosis factor a production. Thiopental is one of the most widely used drugs for rapid induction of anaesthesia. During experimental studies on the treatment of acute pancreatitis, we observed that when pentoxifylline was administered after anaesthesia with thiopental, most of the rats exhibited dyspnea, signs of pulmonary oedema and died. The aim of the work described here was to investigate the cause of the unexpected toxic effect of the combined treatment wit…
